Centos 7 installation - xcauth cli working - but Nextcloud won't login chat #81

deusoz · 2019-07-24T14:28:48Z

Hi, I'm running on a budget OpenVZ instance GNU kernel 2.6 with miminal Centos 7.
Nextcloud 16 with Ejabberd 18
Centos 7 comes with python 2.7 preinstalled.

I installed python 3 according to https://linuxize.com/post/how-to-install-python-3-on-centos-7/
Installed Berkeley Database so that python- bsddb3 module could be installed.
http://www.linuxfromscratch.org/blfs/view/svn/server/db.html

All done and so I was able to install from source the latest version of xcauth
sudo git clone https://github.com/jsxc/xmpp-cloud-auth

Revised Makefile, here is the diff ouput

_BTW After the build and failed tests, I manually added user ejabberd to group xcauth and vice versa to see if that was my issue, this command that I commented out above perplexes me "adduser ejabberd xcauth;" I just get the "--help" screen when I try that command on my Centos server _

Here is my xcauth.conf

OK so, let's test this baby...

command line, wow! it seems to work... it seems to affirm that user db5d has a matching pw.

True

But when I try via Nextcloud... does not work.

I'm not getting any log entries in my /var/log/xcauth/ folder which has permissions shown below. I tried changing owner to root, apache and xcauth, but still no logs appear.

drw-rw-r-x  2 xcauth xcauth 4096 jul 23 18:16 .
drwxr-xr-x 11 root   root   4096 jul 23 18:16 ..

Here are bosh stanzas after failed login attempt.

And so it says I have invalid user name or password, yet am using correct un/pw.

Thank you for you time in helping troubleshoot this!

Maybe only has to do with permissions somewhere?

I am having the same issue. xcauth works properly from the command line when executed with user permissions of ejabberd but fails to start as a child process. I have disabled the apparmor profile and the error continues to occur.

Setup:

Debian 10 (no systemd) - I generally prefer to use SysVinit
- ejabberd 18.12.1-2~bpo9+1 (from stretch backports)
xcauth compiled from git (using make install)
- (the debian package requires systemd which is why I manually compiled it)

ejabberd.yml auth config:

## Auth method (external to connect to Nextcloud)
auth_method: external
extauth_program: "/usr/sbin/xcauth"
auth_use_cache: false

I notice that the docs say that we may need a wrapper, xcauth.sh as the extauth_program due to library issues but this file is not available in the repository as far as I can see. Nor is it available from the xcauth.deb (I tried extracting it from the .deb)

Any ideas how to fix this issue?

edit

to clarify that this occurred on Debian Buster (10)

I think I got the same problem after debian buster upgrade. I didn't find a solution and needed to restore the server backup with debian stretch.

zeigerpuppy · 2019-09-15T22:03:42Z

Looks like it's definitely an issue in Buster (I checked and the server it was not working on was running Buster). Looks like staying on Stretch is the way to go currently.

MarcelWaldvogel · 2019-09-19T13:54:09Z

Are there any error messages in /var/log/xcauth/*?

I also fixed #83 today, which was related to startup on newer versions of Debian/Ubuntu. Maybe updating hepls?
